Description of data:
The ASCII file econ_j.txt contain the three data series used
to generate the results in Geroski and Walters (1995) "Innovative
Activity over the Business Cycle", EJ, 105:431, 916-928.
The series labelled PAT is from the Science Policy Research
Unit (SPRU) at the University of Sussex and represents an
annual count of the number of patents awarded by the United
States Patents and Trademarks Office to UK registered companies
from 1883 to 1992.
The series labelled INN is also from SPRU and represents
an annual count of innovations defined as "the successful
commercial introduction of new or improved products, processes
and materials introduced in Britain between 1945 and 1983"
(see Geroski and Walters ref to Townsend et al (1981) "Innovations
in Britain since 1945" or Pavitt et al (1987) "The
Size Distribution of Innovating Firms in the UK, 1945-1985",
Journal of Industrial Economics, 35, 297-316 for more details).
The data were generated as part of a large scale, one off
study into the incidence of post War innovative activity in
the UK.
The series labelled OUT is from Table 15 "Index of Output
of the Production Industries (Total Manufacturing Industry)",
CSO Economic Trends Annual Supplement 1992, series DVIS and
represents an index of manufacturing output from 1948 to 1992.
Additionally, the first paragraph of section II.4 on page
924 mentions replicating the reported results using three
other measures of demand. The first is an index of GDP at
current factor cost (1985=100), the second GDP at constant
factor cost in 1985 prices and the third an index of non-oil
manufacturing output. These three series are all taken from
CSO Economic Trends Annual Supplement 1992.
Moreover, the second paragraph on page 925 mentions relating
the longest patents sample to a longer demand sample. The
post 1947 data for this demand sample is the same as OUT and
that for the period 1883-1947 is taken from "Total Industrial
Production" in Feinstein (1972) Statistical Tables of
National Income, Expenditure and Output of the UK, 1855-1965,
Cambridge University Press, and spliced to the later sample.
This series includes Irish industrial production (always less
than 2% of total UK industrial production) until 1920.
All regression results reported use Ordinary Least Squares
estimators and data analysis was conducted using TSP 4.3,
Stata 4.0, PcFiml 8.0 and REG-X (Professor Steven Hall's econometrics
package which can be downloaded free of charge from the LBS
Web page http://www.lbs.lon.ac.uk).
